My favorite is my Browning Nomad... this was my dad's plinker and it's still dead accurate and loads of fun to shoot. I recently bought a Ruger Single Six and am having lots of fun with it as well. I love the 22 Magnum chamber option. I have a friend who has asked me to sell her deceased husband's Ruger Mark I, so I've done a bit of shooting with it to try it out. Also a very nice gun, lots of fun to shoot. Once you get the hang of its disassembly and re-assembly I give it two thumbs up as well.
So yes, I am enjoying going to the range and shooting lots of 22's at a low price, but I always make sure to bring along my S&W 686 and some 357 mags for the big bang thrill.
Finally, there's another way I keep up my target skills without even a trip to the range: I've got a S&W 586 air pistol (CO2 cartridge, ten pellet magazine) that is incredibly accurate, feels just like a real 586 (weight, size... just not the recoil). I can shoot this for hours and have lots of fun with nearly zero cost! Highly recommended.
